Environmental Angst



Summer vacations have greatly slowed my ability to string together enough sentences to form a post for My Porch. However, I didn't want to leave my millions of readers hanging out with nothing to read.

One of my more vivid nightmares is about water shortages and the damage we are doing to the earth's potable water. What about the millions of people who have chosen to live in deserts where there is no reasonable local water supply? In some future crisis will the electoral power of these burgeoning population centers overwhelm their less powerful neighbors upstream, commandeering billions of gallons of water just so some snowbird in Phoenix can have a patch of green lawn?
